Bottom Line:
The remaining coordination sites are occupied by two N atoms of a 2,2'-bipyridine (bipy) and two O atoms of an anthracene-9-carboxyl-ate ligand.The six anthracene-9-carboxyl-ate groups coordinate each La(III )atom in three different ways.Adjacent discrete dinuclear units are arranged into a one-dimensional chain along the [111] direction by inter-molecular π-π stacking inter-actions, with a centroid-centroid separation of 3.704 (7) Å.

ABSTRACTThe title complex, [La(2)(C(15)H(9)O(2))(6)(C(10)H(8)N(2))(2)], has a centrosymmetric binuclear cage structure in which two La(III )atoms are both nine-coordinated and bridged by four anthracene-9-carboxyl-ate ligands, with an La⋯La separation of 4.0880 (4) Å. The remaining coordination sites are occupied by two N atoms of a 2,2'-bipyridine (bipy) and two O atoms of an anthracene-9-carboxyl-ate ligand. The six anthracene-9-carboxyl-ate groups coordinate each La(III )atom in three different ways.

Fap1: The molecular structure of complex (I). Displacement ellipsoids are drawn at the 30% probability level. Atoms labelled with the suffix A are generated by the symmetry operation (1 - x, 1 - y, 1 - z). For the sake of clarity, all H atoms have been omitted.
